The aim of this study was to evaluate the relation among nominal realism and reading, writing as well as mathematics activities. Participants were thirty-nine children of the first, second and fourth grades and fifteen adults at the first stage of the first cycle of adult and young education. The tasks used were reading, spelling words and pseudo-words, nominal realism and mathematics. Results indicate that nominal realism is significantly related to reading, writing and mathematics. These findings reaffirm the interference of nominal realism in reading and spelling activities, and indicate also a strong correlation with mathematical abilities.
